What is aluminium?

Aluminium is a metal that has the ability to be combined with other metals while still keeping its purity. You can find it in items like airplanes, cars, and even your kitchen pots. It’s often used because it’s lightweight and strong, which means it’s perfect for things like car frames or fuel tanks.

What is aluminium's atomic number?

Aluminium has 11 protons, 11 electrons and 12 neutrons. Which makes it a member of group 13, period 3 on the periodic table, with a symbol Al.

What is the atomic weight of aluminum?

Aluminium is a metal that is not only cheap, but also lightweight.

Aluminum’s atomic number is thirteen. This means that it has thirteen protons in its nucleus. It has an atomic weight of 26.9815, meaning that each atom of aluminum weighs 26.9815 atomic mass units.

How many valence electrons does aluminum have?

Valence electrons are the electrons in an atom or molecule that can participate in chemical bonds. They are also the most mobile of all the electrons.

This question is not asking about aluminum specifically, but rather is asking about how many valance electrons any metal will have.

Aluminum is a metal with three valence electrons.

Aluminum is an element that contains thirteen protons in its nucleus and thirteen electrons in orbit around it. It has three valence electrons so it is always engaged with other atoms to form compounds.

Aluminum atoms contain 13 electrons and 13 protons. There are 3 valence electrons in the outer shell.
